Transferability and Hardness of Supervised Classification Tasks [PDF]

open access: yesIEEE International Conference on Computer Vision, 2019
We propose a novel approach for estimating the difficulty and transferability of supervised classification tasks. Unlike previous work, our approach is solution agnostic and does not require or assume trained models.

The hardness of conditional independence testing and the generalised covariance measure [PDF]

open access: yesAnnals of Statistics, 2018
It is a common saying that testing for conditional independence, i.e., testing whether whether two random vectors $X$ and $Y$ are independent, given $Z$, is a hard statistical problem if $Z$ is a continuous random variable (or vector).
